COMBINED RUNNER AND ROLLER SKATE.

SPECIFICATION forming part of Letters Patent No. 226,835, dated April27, 1880.

Application filed January 5, 1880.

To all whom it may concern:

Be it known that I, EDWIN OHEs'rERMAN, of the city of Philadelphia andState of Pennsylvania, have invented a new and useful Improvement inCombined Runner and Roller Skate, which improvement is fully set forthin the following specification and accompanying drawings.

The object of this invention is to convert an ordinary runner-skate intoa roller-skate without removing the runner.

The invention consists of rollers and axles, one or more, adapted to beattached to a runner-skate without removing the runner; also, ofroller-frames and rollers, one or more, and a clamp or clamps, by whichsaid roller-frames may be fastened to or removed from the runner of askate; also, of the combination, with a runner-skate, of axles androllers, one or more, in such manner that said axles and rollers may bereadily attached or detached without removing the runner from its frameand without impairing said runner for its primal use.

Referring to the drawings, Figure 1 is a perspective, showing arunner-skate with my invention attached. Fig. 2 is a vertical section ofmy invention. Fig. 3 is a modification of my invention, showing the axlepivoted to the clamp to facilitate a curved movement.

A represents an ordinary runner-skate. A is the sole-plate. B is aclamp, in the present case made with an axle or spindle, B, projectingon each side, which spindle is made hollow for the double purpose ofdiminishing its weight and to admit a screw by which the axles areattached to the skate A.

b is a collar formed on the axles. I) are holes for the linchpin, whichwill be hereinafter described. I) is a female screw formed in the hollowaxle, and c is a screw by which the axle is clamped to the skate A.

G are rollers or wheels which revolve on the axles, and c are linchpinsby which said rollers are held on the axles. These linchpins are made ofthe form shown, the distance between the two shoulders being a littleless than the diameter of the axles. The two ends or points projectingtoward each other from said shoulders are of a length equal to thethickness of the shell of the axle. When the roller is put on its axleand the linchpin sprung into its position said linchpin will pressagainst the axle with force sufficient to hold its points in the holesand retain the rollers on said axles, and the hollow in the axles willbe left unobstructed for the application of the proper tool to turn theset-screw, by which the axles B are attached to or detached from theskate A.

Fig. 3 shows the clamp and axle made in separate pieces. The clamp has apivot ex tending downward, and the axle is enlarged and provided With atubular bearing in the middle, so that the axle may turn on the pivot ofthe clamp to facilitate a curved movement If desired, a clamp may beextended upward from the axle and fastened to the edges of thesole-plate instead of to the runner; or the clamp may be formed withclips or hooks to fit over the top edge of the soleplate, in which casethe clamp would be passed up over the runner to the top of the soleplateat its narrowest part, and then moved forward or backward to the widerparts, and when in the right position a set-screw would be tightened andthe clamp, wit-h its axle and rollers, be firmly'attached to thesole-plate.

This and other modifications may be made without departing from thespirit of this invention.

It will be readily seen that the herein-described attachment may beapplied to any ordinary runner-skate by simply tightening the set-screw,and removed by loosening said screw, and that no alteration is requiredin the runner-skate; neither is said skate in any way injured.

Having described my invention, what Iclaim as new, and desire to secureby Letters Patent, is

1. In combination with axles having rollers attached thereto, a clamp,B, and set-screw c, where by said axles may be readily fastened to orremoved from the runner of a skate without removing it from thesole-plate or impairing its use as a runner, substantially as set forth.

In combination with the skate-runner A, a hollow axle, B, havingclamp B, female screw b and set-screw c, with rollers (l attaehed tosaid axle, substantially as and for ing the runner from the sole-plateor impairthe purpose described. ing its use, substantially as and forthe pur- 3.
